People know what they want. They're not complaining that it's too different, they're complaining that it's poorly designed and presented.
If there was a sense of style to the robot beyond staking blocks, people would probably be all over it, since there are design cues that I can get behind. But it's so basic and dull that of course people would complain.

I would say you're missing a C, but you literally do stake blocks for this thing alone with stacking them.
